Answer:
2
Step-by-step explanation:
-3 log₂ (-n + 10) = -16+7
-3 log₂ (-n + 10) = -9
log₂ (-n + 10) = -9/-3
log₂ (-n + 10) = 3
-n + 10 = 2^3
-n + 10 = 8
n=2
Answer:
the probability of drawing a pink rose from the bunch of roses is 25%
Step-by-step explanation:
assuming that each rose es equally likely to be chosen then the probability of picking one pink rose is
probability = number of pink roses / total number of roses = 3 / (5+3+2+2) = 3/12 = 0.25 (25%)
then the probability is 25%
